米国申請者への短い回答:実際に持っているカードはすべて使えます。Visa、Mastercard、American Express、Discover(クレジットカードでもデビットカードでも)、PayPal、Apple Pay、Google Payはすべて、80ドル(観光)または90ドル(ビジネス)のeVisaをクリアし、米ドルで請求されます。以下は、ネットワークごとの受け入れ可否とカードが拒否される原因の詳細です。

US citizens can pay with any major card network — Visa, Mastercard, American Express, or Discover, as either a credit or debit card — plus the PayPal, Apple Pay, and Google Pay wallets. You pay the $80 USD all-in Tourist eVisa or $90 USD Business eVisa price, billed in US dollars, with no separate processing surcharge at the final step. A US debit card clears exactly like a credit card as long as it is enabled for international online purchases and the full amount is available when you confirm. Because the charge settles in USD there is nothing to convert, though a few US banks add their own foreign-transaction fee of roughly 1 to 3 percent. The most common payment snag for Americans is their own bank declining an unfamiliar international charge as suspected fraud, which a 30-second heads-up to your card issuer prevents.
If you can use a card to buy something online from home, you can almost certainly use it to pay for your Cambodia eVisa. The checkout accepts all four card networks US travelers carry — Visa, Mastercard, American Express, and Discover — as credit or debit, and it also takes PayPal, Apple Pay, and Google Pay. You pay $80 all-in for a Tourist eVisa or $90 for a Business eVisa, in US dollars, and the number you confirm is the number on your statement.
The reason Americans ask "will my card even work?" before applying is usually history, not Cambodia. Travelers have been stung by overseas checkout pages that quote one figure and bill another, by surprise "service" lines added at the final screen, and by cards that bounce with no explanation. This guide goes network by network, spells out how debit behaves differently from credit, shows what the charge looks like on a US statement, and lists the short set of reasons a card gets stopped so you can clear it in seconds.
Below you will find the accepted card networks one at a time, the digital wallets, how debit cards behave, what shows on your statement in US dollars, and the handful of fixes for a declined payment. When you are ready, you can apply online in about ten minutes. For the full picture of every entry rule, document, and fee, our Cambodia visa guide for United States citizens is the canonical reference.
What matters at checkout is the network logo on the front of your card — Visa, Mastercard, American Express, or Discover — not the bank that issued it. A regional credit-union card runs the same as a major-issuer card on the same network. Here is how each one behaves for a US applicant.
These two cover the vast majority of US applicants and they are handled identically. Whether it is a Chase Sapphire, a Capital One Venture, a Bank of America cash-back card, or a plain checking-account debit card with a Visa or Mastercard mark, it goes through the same way. There is no special enrollment, no separate verification rail — you enter the card, confirm the USD total, and the approved eVisa lands by email within 3–5 days.
Both are accepted on the US checkout, which is worth saying plainly because AmEx and Discover are sometimes refused on overseas travel sites. They are not refused here. The only thing to watch is that a handful of American Express cards apply their own foreign-transaction fee on a charge processed through an overseas merchant — that is the card issuer, not the visa price, and it is the same fee you would see on any international purchase with that card.

You do not need a credit card to pay for a Cambodia eVisa. A US debit card is accepted exactly like a credit card, and if you would rather not type any card number at all, the checkout takes PayPal, Apple Pay, and Google Pay. Each has one small thing worth knowing before you confirm.
If your debit card carries a Visa or Mastercard logo and is switched on for international online purchases, it clears the same as a credit card. The one difference is timing: a debit charge draws the full $80 or $90 out of your linked account the moment you confirm, rather than against a credit line you settle later. So the practical rule for debit is simply that the money has to be there that day. If your balance is thin when you hit confirm, the payment fails even though the card itself is perfectly valid — and that failure is funds, not the card being rejected.
The three wallets route through whatever you already have linked, so an Apple Pay payment charges the card in your Wallet app, a Google Pay payment charges your linked card, and a PayPal payment draws on your PayPal balance or backup funding source. The quiet advantage for a cautious cardholder is tokenization: with a wallet, your raw card number never touches the checkout at all. If you would rather keep card details off a travel site entirely, a wallet is the clean way to pay.
For US applicants who want to compare every option side by side before they decide, our Cambodia eVisa payment methods guide for Americans lays out each card and wallet with the same level of detail. Whichever method you pick, the price is the same — there is no surcharge for paying one way over another.

The Cambodia eVisa is priced and billed in US dollars. When you confirm an $80 Tourist eVisa, your card is charged $80 USD — there is no local-currency conversion happening at checkout, and no dynamic-currency-conversion prompt asking whether you want to "pay in your home currency" at a marked-up rate. For a US cardholder already paying in their own currency, that removes the single most common place travelers quietly lose a few dollars to a bad exchange rate.
On your statement the visa appears as one clean line for the amount you confirmed. There is no second "processing" or "service" line stacked on afterward — the all-in price is a single charge, and our guide to what is included in the Cambodia eVisa price for Americans breaks down everything that single figure covers. If you also pay for the e-Arrival Card, it shows as its own separate $20 line, because it is a separate filing rather than a hidden add-on to the visa. Two tidy lines — one for the visa, one for the e-Arrival Card — is exactly what you should expect to see, and it is the fastest way to confirm nothing extra was slipped in.
見積りに含まれていない唯一の変数はお客様自身の銀行です。請求は米ドルで行われますが、一部のアメリカのカード発行体は海外Merchant経由で処理された支払いを国際取引と見なし、約1〜3%の外国取引手数料を追加します。これはビザの価格が变动したものではなく、銀行があなたに追加で請求しているものであり、外国取引手数料無料のカードなら完全に回避できます。アメリカの申請者向けのカンボジアeVisa外国取引手数料ガイドでは、この手数料が発生するタイミングと、どのアメリカの日常利用可能なカード牌免できるかを说明しています。

アメリカのカードがカンボジアeVisaのチェックアウトで失敗した場合、原因はvisaサイトにあることは几乎なく、几乎常にカード側で発生する問題であり、数秒で解消されます。前もって簡単なリストを知っておくことで、申請が壊れたと assumesする 而是 calmly修正できます。
最も効果的な方法は、申請を開始する前に銀行に国際オンライン取引を行う予定であることを伝えることです。アメリカの銀行アプリのほとんどは、30秒で完了するワンプッシュの旅行通知機能を備えています。それでも支払いが通らない場合、アメリカ人向けのカンボジアビザカード拒否解消ガイドですべての原因と正確な再試行手順を説明します。
Once your visa is paid and approved, there is one more small payment to plan for. Every air arrival in 2026 also files the Cambodia e-Arrival Card — a digital arrival declaration of 14 fields covering your passport, flight, and accommodation details, submitted within 7 days before you land. Verified through us, it is a separate $20 USD payment, and you can pay it on the same card or wallet you used for the visa with no extra surcharge. Budget the $20 per traveler alongside the visa so it is not a surprise.
